Morning + coffee = no heart palpations
For those of you who can’t function without your morning cup of Joe, good news - new research has dismissed claims that coffee can give you heart palpations. And what’s more it’s even been found that a caffeine boost in the morning can be good for cardiovascular health. Get that cafetiere on!
Scientists from the University of California, San Francisco, looked at 1,388 randomly selected participants, excluding those with persistent extra heartbeats, and analysed their coffee, tea and chocolate consumption, with 61 per cent of them enjoying more than one caffeinated product daily. However there was no difference found in the number of PACs (premature atrial contractions, heartbeat beating too fast) or PVCs (premature ventricular contractions, where the heart skips a beat) per hour across levels of coffee, tea and chocolate intake. Furthermore frequent consumption of these products was not associated with extra heartbeats.
“Clinical recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart's cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits,” said Dr Gregory Marcus, who was behind the study.
“Given our recent work demonstrating that extra heartbeats can be dangerous, this finding is especially relevant.”
The results have been published in the Journal of the American Heart Association.
Lead author Shalini Dixit points out that further research needs to be done in the area though.
“This was the first community-based sample to look at the impact of caffeine on extra heartbeats, as previous studies looked at people with known arrhythmias,” Shalini explained.
“Whether acute consumption of these caffeinated products affects extra heartbeats requires further study.”
